This manual is intended to assist New York State agencies in the "Community Integration Project in Aging and Developmental Disabilities." The first section chronicles experiences of various agencies in carrying out long-term planning, training, and program development for this population. The second section explains federal developmental disabilities statutes, common aging terms, effects of aging on specific disabilities, and incidence estimates. Other sections discuss federal acts that directly affect older persons with developmental disabilities; potential barriers to integration; strategies for overcoming these barriers (including policy, attitudinal, information, communication, and financial barriers); guidance on state and area plan requirements including gathering information and plan development; activities that can be undertaken by state developmental disabilities planning councils, state units on aging, and state developmental disabilities agencies to bridge systems and build partnerships; how to provide for short-term and long-term training needs including inservice activities and course infusion at the university level; and program options for this population including day programs, retirement, family supports, housing options, and adaptations of physical environments. Of special interest to educators is chapter 8 entitled: Developing Training and Education Programs". Appendices include data from demonstration projects, population tables, sample agreements, a list of national associations, and a list of 36 bibliographic resources. (DB)
